Vibratory Screen De-Stoner & Classifier
A heavy-duty mechanical separator that uses reciprocating vibratory motion and multi-layered sieves to grade raw grain by physical dimensions and to separate high-density impurities — stones, clods, and mud balls — from the grain stream. Positioned at the head of the line, it protects every downstream machine from abrasive damage and delivers a clean, uniformly-sized feed.

What sets this machine apart.
Multi-deck classification
Stacked sieve decks scalp oversize trash and grade kernels by dimension in a single pass.
Gravity de-stoning
An inclined, air-fluidised deck floats grain over stones so high-density impurities are walked off separately.
Tuned vibratory drive
Adjustable stroke and angle let you dial in residence time for different crops and moisture levels.
Quick-change screens
Tool-light sieve swaps let a single frame switch between paddy, wheat, pulses, and other grains.
